Cryptographically sign all executables and DLLs

McAfee Application and Change Control (MACC) is a suite of security software used by the Navy to protect their servers. MACC protects the OS by blocking executable files (.exe, .dll, .jar, etc) unless they have been "solidified" and permitted to execute. If the executable is changed, a new SHA256 hash must be generated and provided to the MACC admins for the changed executable to be allowed.

MACC's heuristic module has recently started flagging multiple Information Server DLLs as "suspicious" and blocking them from executing, even after they were solidified, which effectively halts all jobs from running on that server. According to the MACC documentation, cryptographically signed executables are trusted and will not be blocked by its heuristics.

I am requesting that IBM update all executable files that can be cryptographically signed, so MACC (or other security suites) will be less likely to freak out about these DLLs.

See pages 33-34 of the MACC 6.1 product guide for an example.

Specific DLLs that I have seen blocked so far (this list has changed over time):

  • G:\IBM\InformationServer\Server\PXEngine\bin\liborchbuildopnt.dll

  • G:\IBM\InformationServer\Server\PXEngine\bin\liborchcorent.dll

  • G:\IBM\InformationServer\Server\PXEngine\bin\liborchstatnt.dll

  • G:\IBM\InformationServer\Clients\Classic\dssingleton.dll
